My boyfriend was raped & murdered by sick strangers days after 4th baby was born…tragic memento is all they have of him

BOBBIE Cowan felt the world caving in on her when she received the devastating news that her partner - the father of her kids - had been taken from her in the most sickening way imaginable. Calum Simpson was just 24 when he was attacked and murdered by twisted killers Dylan Brister and Cameron Allan who spiked his drink and then raped him as he lay dying. Calum’s partner, Bobbie Cowan, had given birth to the couple’s daughter, Lyla, just 11 days before the murder and is now raising their four children alone.

Now, she has bravely spoken about the anguish she has had to endure since Calum's senseless murder. Bobbie, 26, from Fife, says: “The night Calum went out, we’d had a few words and he left on a bad note. It was nothing serious but I’ll always regret that because they were the last words we ever spoke to each other. “When he didn’t come home, I felt annoyed that he’d left me to look after the children on my own. I could never have imagined what was coming next.

“My world fell apart when the police came to tell me he was dead. When I found out he’d been attacked and raped, I was sickened. He must have suffered so much. “The children and I miss him terribly. They each have a teddy bear which has Calum’s voice inside, saying: ‘I love you and I will see you soon.’ It breaks my heart.”. Calum and Bobbie got together at a party in 2015, when she was aged 17 and he was 18.

Bobbie says: “I really fell for him he was funny and kind, and so good looking.”. The couple moved in together and their son, Calum, now eight, was born in August 2016, followed by a little girl, Mirren, in March 2018. Bobbie says: “Calum was a fun dad, forever tickling the kids and making them laugh. I was the sensible one. We were very much in love but we bickered a lot too, because we were only young.

“With two little ones, money was tight and we were so busy. We started to pick at each other and argue. Suddenly, it felt like a lot of pressure, running a home and raising a family. We were still so young.”. The couple split and Bobbie had a baby daughter, Romi, with a new partner. But her relationship did not last, and she and Calum found themselves back together. Bobbie says: “I never stopped loving Calum. When he met Romi, he treated her as his own, he was lovely with her, which really made me realise what a good man he was.

“He was round every day, helping out, looking after the kids. I felt myself falling in love with him all over again.”. The couple reunited in May 2020, when Romi was eight months old and in November 2021, Bobbie gave birth to a fourth child, Lyla. She says: “We were both over the moon when she was born. But Lyla was ill with an infection after she was born and was in hospital for nearly a week. "It was a really stressful time. When I came home, I wasn’t well, I’d had stitches and I was struggling.

“We had four little ones to look after and we had a silly argument about the housework and the kids; it was nothing. "Calum said he was going to see a friend and I expected he’d be back either late at night or in the morning. "I was a bit annoyed he’d left me to look after the kids on my own. I feel terrible about that now but I couldn’t have known.”. The next afternoon, the police came to tell Bobbie that Calum was dead.

She says: “I had Lyla in my arms and they took their helmets off and asked me to sit down which made me panic. “When they said Calum was dead, I just refused to believe them. They said he was at an address I’d never heard of, so I thought they had got it wrong. "It was only when they described his tattoo that I realised. I was shell-shocked. “I was allowed to see him through the glass at the morgue. It was heartbreaking. I could hardly even take in that he was gone. He was just 24 years old.

"He had his whole life ahead of him; four children and a partner who adored him. “Lyla was only 11 days old. I realised she’d never know her daddy. I’d taken a couple of photos of her and Calum, before we left hospital. Now, I realised, they were all we had. “This was supposed to be a wonderful, precious time, welcoming our new baby into the family. Instead, I was trapped in a horrific nightmare.”.

But there was more heartache to come. The police told Bobbie that Calum had been murdered by two men he had never met before. They had secretly drugged his drinks and after he fell unconscious, they raped him and left him to die. She says: “It didn’t make any sense. Why would one human being do that to another, for absolutely no reason at all?”. In October 2024, the High Court in Dundee was told that Dylan Brister and Cameron Allan secretly slipped drugs into Calum’s drinks, leaving him unconscious, before tying him up with rope and subjecting him to a sexual assault which they recorded on a mobile phone.
